Next, the gamma ray burst (GRB) in the universe has been detected in 1967, and the GRB discovery has been published in 1973 [1]}. Since then, to explain the GRB, there have been extremely lots of theoretical models. For a statistical survey of the GRB bibliography, see Ref. [2]} for instance. If the GRB sources were from within the Milky Way, they would be strongly concentrated near the galactic plane. The absence of any such pattern in the GRB has suggested a strong evidence that the GRB can come from beyond our own galaxy. The intense radiation flare of most detected GRB has been then assumed to emerge from a supernova, during a high-mass star
implodes to construct a neutron star or a black hole.
